Dave is confusing locks with the strikes. What I referred to was the
conventional approach of having the component that opens be the _strike_,
not the lock, with a hard-wired interface to a HA system that logs who
enters when as the original poster desired.

But this wouldn't meet the original poster's desire to be able to log who
entered and when. The deadbolts Dave refers to do not, ABIK, have a way of
communicating with HA software.
